How Installing Energy-Efficient Windows in Windham Saves You Money

By switching to energy-efficient windows, you can benefit in several ways, such as:

  • Save money on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $457 annually on your energy bills in Windham.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Windham, that's about 147 pounds per year on average.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Windham

Windows come in varying styles, shapes and purposes, so costs and services will vary remarkably based on several factors. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

On average, Windham homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at about $600. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Windham homeowners $457+ per year after replacing single-pane windows.

Asking for free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

The first step of a window installation is to decide whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're not sure which kind of window installation service you should get, your installer can help you out. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Windham

In our hunt to find the most reliable, eco-friendly window installers in Windham, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of parts, warranty, cost, professionalism, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Windham's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Windham window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Windham, CT Window Replacement FAQs

How much does window installation cost?

The average cost to install a window ranges between $450 and $650. There are a variety of factors that influence the cost, which include local labor costs, styles and sizes of windows, the number of windows, how energy-efficient the windows are, your property's location and the materials used in designing the windows.

Which type of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

When should I use a window installation company?

Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.

How long does it generally take to install windows?

Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
